Application tiled September 17,1904. Serial No. 224.842.

To all, whom, it may concer-71,.

Be it known that I, JOHN D. LEFFEL, a citizen of the United States,residing at Johnstown, in the county of Cambria and State of.

Pennsylvania, have invented new and useful Improvements in Planes, ofwhich the following is a specification.v

f novel features of construction and combination of parts more fullyhereinafter described.

ln the accompanying drawings, Figure 1 is a side elevation of a planeembodying the invention. Fig. 2 is a front view of the same, partly insection, illustrating the device in operation, the section being takenon the line 2 2 of Fig. 1. 3 is an enlarged detail sec- -tion of the guiing member, showing the same in active position. Fig. 4 is a similarview showing the member in normal inactive position.

Referring to the drawings, 1 designates the body of the plane, havingits lower bearin face or sole slightly curved transversely an providedwith uprising side walls or flanges 2, upon one of which is fixed atubular barrel or sleeve 3, adapted to receive a vertically-movablemember or plunger 4, carrying at its lower end a guide plate or head 5,the inner vertical face of which travels smoothly over the outer face ofthe adjacent side iiange 2. The plunger-rod or member 4, which isprovided at its upper end with a head 6, is adapted to be presseddownward for maintaining the guide member 5 in active position by meansof a spring 7, arranged within the barrel 3 and coiled upon the rod 4between fixed collars or abutments 3 4, provided on the barrel and rod,respectively, and forming terminal bearings for the spring, whereby thelatter in expanding will move the guide-head into action. The rod 4further has a laterally-projecting stud or stop 8, adapted normally toengage the upper edge of the barrel 3 for maintainin the guide in normalelevated position, t e stud being designed to travel in a verticalopening or slot 9, formed through the wall of the barrel when it is deysired to depress the plunger for moving the guide to active position.

The plane is provided with the usual handle 10 and with a cutting-blade11, the lower active edge of which is convexedly curved transversely, asshown in Fig. 2, whereby the plane in o eration will form in the rearface of the mo ding shallow troughs or channels 12 for the usual purposeof reducing the contacting surface of the molding when 'employed in theconstruction of window and door frames. i

ln practice when the plane is initially brought into operation theplunger 4 is rotated until the pin 8 comes into register with slot 9,whereupon the spring 7 will act for automatically moving the plungerdownward and pro'ecting the guide member 5 below the plane of the lowerface of the tool, as illustrated in Fig. .2, whereby during travel ofthe plane longitudinal of the molding the member 5 will bear upon theouter marginal edge of the latter, and thereby guide the plane in itsmovements and at the same time prevent the plane slipping and destroyingthe narrow bearing-face formed adjacent to the longitudinal edge of themolding. After formation of the first channel 12 adjacent the edge ofthe molding the plunger may, by grasping the head 6, be raised to bringthe guard to normal position, with its lower edge flush with that of theplane, and may be fixed in 'this position by a slight rotation of theplunger for moving the pin out of register with slot 9, as heretoforeexplained.

From the foregoing it is apparent that l produce a simple deviceadmirably adapted for the attainment of the ends in view, it beingunderstood that minor changes in the details herein set forth may beresorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is 1. Thecombination with a plane, of a tubular sleeve carried thereby andslotted longitudinally, a longitudinal y-movable lunger mounted in thesleeve, a guide mem er carried by the plunger, a stud provided on thelatter and adapted to engage the end edge of the sleeve for maintainingthe plunger in normalretracted position, and a spring acting upon and toproject the plunger for moving IOO IIO

the guide member to active position, the stud being adapted during suchmovement of the plunger to travel in the slot.

2. The combination with a plane, of a guide member operatively connectedthere- With and adapted to normally lie in a plane above and to beprojected below the sole of the plane for and to bear upon the side of abody for guiding the plane in its movements thereover, means for movingthe guide member to active position, and means for locking the member ininactive posi tion.

3. The combination with a plane, of a guide member operatively connectedthere- With and adapted to be projected below the sole of the plane inposition to bear upon the side of the body for guiding the plane in itsmovement thereover, a spring for automatically moving the member toactive projected position, and means for locking the member in normal,inactive position in a plane above the sole of the plane.

In testimony whereof I alix my signature in presence of tWo Witnesses.
